[Xen-users] Going crazy with Xen and SATA on AMD64

["Sean Mahrt" <sean.mahrt@xxxxxxxxxxxxx>]

OK, so I'm no noobie to linux, and I finally got softraid and SATA and LVM and AMD64 somewhat behaving.  Now the goal is to have Xen on this athon64 also (3000).  I have a Promise TX2 card with 2 300GB SATA 2.

 

If I build the kernel with arch=x86_64 and disable Xen, all is good.  Drives are detected and raid comes up and ACPI has virtual IRQ's for the promise controller.

 

But if I set the arch to x86-xen, and enable Xen, I get the exact same problem as was posted in this message:

basically the following bad stuff happens and it doesn't see the SATA disks:

 

ata1: SATA max UDMA/133 cmd 0xFE00 ctl 0xFE12 bmdma 0xFEA0 irq 5
ata2: SATA max UDMA/133 cmd 0xFE20 ctl 0xFE32 bmdma 0xFEA8 irq 5
ata1: dev 0 ATA-6, max UDMA/133, 78125000 sectors: LBA
ata1: qc timeout (cmd 0xef)                             <-- bad

 

Now, I would like to get this running, as I put probably 50 hours fighting with raid/lvm/amd64 testing for bad hardware, 3 different boards, etc (still can't pull a drive suddenly and not have it crash).

 

What's killing me is that it seems something to do with ACIP.  Irq steering?  I think this is 2.6.16.18 (gentoo).  What would you like to see?  the dmesg when it doesn't work may be a pain...
